Method: In addition, we defined a list of minor RPV-RAMs that have been observed in in vitro or in vivo selection studies and are included in one or more of clinically widely used genotypic resistance interpretation algorithms ANRS (V24), Rega (V9.1.0), and HIVdb (V7.0.1), encompassing V90I, A98G, L100I/V, K101H/Q/T, K103R/S, V106A/I, V108I, E138S, V179D/E/F/I/T, Y181F/G/S, Y188F, V189I, G190A/C/E/Q/S/T/V, and M230V
Role of Rilpivirine and Etravirine in Efavirenz and Nevirapine-Based Regimens Failure in a Resource-Limited Country: A Cross- Sectional Study.
Method: RT-RAMs were identified and analyzed by using the Stanford Drug Resistance Database for V90I, A98G, L100I/V, K101E/P/Q/H/N, K103N/S/T/Q/E/H/R, V106A/M/I, V108I, E138A/K/Q/G/R, V179D/E/T/F/L, Y181C/I/V/S/F/G, M184I, Y188C/H/L/F, G190A/S/E/Q/C/V/T, H221Y,
Geographic and temporal trends in the molecular epidemiology and genetic mechanisms of transmitted HIV-1 drug resistance: an individual-patient- and sequence-level meta-analysis.
Result: Nevirapine and efavirenz resistance were predicted in about 1% and 0.5% of virus samples without NNRTI SDRMs as a result of several minimally polymorphic (e.g., A98G, V108I, and V179D) and rare nonpolymorphic (e.g., E138K, G190Q, F227C, and K238T) NNRTI-resistance mutations.

Abstract: RESULTS: Sixteen mutations at 10 positions were significantly associated with the greatest contribution to reduced phenotypic susceptibility (>=10-fold) to one or more NNRTIs, including: 14 mutations at six positions for nevirapine (K101P, K103N/S, V106A/M, Y181C/I/V, Y188C/L and G190A/E/Q/S); 10 mutations at six positions for efavirenz (L100I, K101P, K103N, V106M, Y188C/L and G190A/E/Q/S); 5 mutations at four positions for etravirine ( PMID: 23840622

Method: Different RT mutations at the same residue were pooled, including the NRTI-resistance mutations D67NG, K70EGQ, L74VI, M184VI, T215YF, K219QE and the NNRTI-resistance mutations K101EH, K103NS, Y188LCH, and G190ASEQ.
Method: The following non-polymorphic ARV-selected mutations were classified as drug resistance mutations (DRM): (i) the NRTI resistance mutations M41L, PMID: 24015311

Result: The most frequently detected mutations were: M184I/V (92.3%), Y181C/I/V (47.1%), T215I/C/F/N/S (38.8%), D67E/G/N (37.3%), K103N/R/S (33.9%), and G190A/Q/S (32.5%).
Identification of drug resistant mutations in HIV-1 CRF07_BC variants selected by nevirapine in vitro.
Discussion: Thus far, about 32 NVP-resistance associated mutations in 17 positions, including 15 major NVP-resistant mutations at 5 positions (K103NST, V106AM, Y181CIV, Y188LHC, G190ASEQ), have been summarized in HIV drug resistance database of Stanford University.
Measuring enzymatic HIV-1 susceptibility to two reverse transcriptase inhibitors as a rapid and simple approach to HIV-1 drug-resistance testing.
Abstract: Enzymatic 3TC resistance correlated well with the presence of M184I/V, and reduced NVP susceptibility was strongly associated with the presence of K103N, Y181C/I, Y188L, and G190A/Q.
Result: Figure 1B shows that the mean DeltaCt for NVP seen in 83 WT isolates was 7.42+-3.18 (range 0.235-15.9) compared to a mean DeltaCt value of 0.484+-0.963 (range -1.85-2.15) seen in 28 NV
Table: G190A/Q
Discussion: Our data also show that the screening Amp-RT format detecting resistance to NVP correlated with the presence of K103N, Y181C/I, Y188L, and G190A/Q.
